Abstract
The urban development-s planning and the rapid population growth require optimal waste service. This study aims to project waste generation in Palangka Raya city for the next 20 years in order to plan sustainable waste management. Estimation of waste generation is made with multiple linear regression models using waste generation, population and real GDRP data in 2014-2018. Based on the analysis, the waste generation model has an index of determination (R square) of 0.988, which means that the number of inhabitants and the real GDRP influence waste generation up to 98.8%, while the value obtained by F test is 84.96 with Sig. 0.012 which means the regression model is suitable. Based on the estimated model, waste handled in the city of Palangkaraya in 2038 would be 232,379.66 m3/year. The increase in waste generation requires the addition of 31 TPS container and 13 units of arm roll trucks in 2038. Furthermore, it also needs performance improvement of garbage transport rites; unless the organic waste is processed into fertilizer and used for agricultural land around the city, then it will reduce the volume of waste transported to landfill.
